. I Application February 24, 1936, Serial No. 65,458

(01. zap-14s The invention relates to a dispensing cap for .bottles andmore especially to a bottle closure and dropper.

The primary object of the invention is the provision of a cap of thischaracter, wherein the same when worn upon the mouth of a bottle willenable the liquid content to be dispensed therefrom in drops and whenthe bottle is in upright position the same will be closed to eliminateleakage of the content of the bottle, the cap being of novelconstruction and the dropping of the liquid is effected by a depressiblebulb fitted with said cap.

Another object of the invention is the provision of a cap of thischaracter, which is extremely simplein construction, thoroughly reliableand efllcient in its operation, neat in appearance, readily and easilyapplied to and removed from a bottle neck, possessing but few parts, andinexpensive to manufacture.

' With these and other objects in view, the invention consists in thefeatures of constructiomcombination and arrangement of parts as will behereinafter more fully described, illustrated in the accompanyingdrawing, which discloses the preferred embodiment of the invention andpointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a fragmentary elevation of a bottle 39 showing the capconstructed in accordance with the invention applied-thereto.

Figure 2 is a sectional view on'the line 2-2 of Figure 1 looking in thedirection of the arrows.

Figure 3 is an elevation partly in section showing the dispensing nippleadjusted for permitting liquid to be dropped from the bottle.

, Figure 4 is a bottom plan view of, the cap removed from the bottle.Similar reference characters indicate correspending parts throughout theseveral views in I the drawing.

Referring to thedrawing in detail, A designates generally a portionoi abottle having an externally threaded mouth end it for the fittingthereon or the dispensing cap constituting the present invention andhereinafter fully described.

This dispensing cap comprises a collar-like. body it formed with aninternally threaded inner end 82 for detachable engagement with the 59mouth end it of the bottle A while the thickened outer end it is formedwith a central dispensing opening iii, the wall of such opening be ingoutwardly flared and covering this outer end is a rubber compressiblebulb it, it having marginally trimaran internal head is name in anannular seat it formed externally in the thickened outer end I! for thecoupling of such bulb with the body H as will be clearly apparent fromFigures 2 and 3 0i thedrawing. f

Thebulb is formed with a central inwardly directed stem l8 terminatingin a conical shaped valve l9 which is normally seated against the innerend of the opening H as provided in the thickened outer end." so thatthis opening I will be closed and on depressing the bulb 15 the openingI will be cleared to permit the discharge of the contents of the bottleA therethrough.

Adjustably threaded laterally in the thickened outer end iii of the bodyI i is a dispensing nipple 20, the socket for the said nipple being incommunication with the opening I! bya passage 2i and this passage isnormally closed by screwing the nipple 20 inwardly in its socket to shutoff the passage 2| therefrom. On unscrewing the nipple 20 from itssocket-the passage 2| is opened so that the contents from .the bottle Acan be dispensed by flow through the opening I, passage 2i and nipple20. The nipple 20 in its.construction is in the form of a dropper spoutfor discharging the contents of the bottle A drop by dropthrough saidnipple when the bottle is inverted and the bulb I5 is depressed.

Normally when the bottle is in an upright position the nipple 20 isscrewed completely within its socket to close the passage 2| so thatleakage from the bottle is prevented even if the same is inverted.

When it is desired to dispense the contents, the nipple 20 is unscrewedfrom its socket and on depressing the bulb i5 the valve I9 is unseatedand such liquid within the bottle is forced therefrom by air throughpressing the bulb 55 for the discharge of liquid through the nipple 263and'the flow of the liquid therethrough can be regulated by adjustmentof said ripple.

What is claimed is:

A clmure of the character described comprising a collar-like bodyopening through opposite ends and having an internally threaded innerend for detachable engagement with c.- bottle neck mouth and having anannular external groove at the other end thereof, a shoulder formedinteriorly of said body to provide a valve seat, an inherently resilientcap-like member covering the outer end of; saidbody and seated in saidgroove for effecting a depressible bulb, a valve depending centrallyfrom said bulb and normally engaging the valve seat, and. a pouringnipple carried by said body and having communication with the bottlemouth at the interior of said body.
